I want to run specific line in a .js file, how to make it right?

source js file:
text

I just want to run this line:
var Jk = JN[‘V’](this[‘Y’][0xced + 0x83 * 0x4a + -0x32ca])
, Jk = Ja[Fh(bc.F)](Jw, Jk, JQ);

and I know “this[‘Y’][0xced + 0x83 * 0x4a + -0x32ca]” refer to string “/portal/main/flight/direct/query”

how to run it in python ? (selenium or whatever can make it right)

I tried selenium, use “execute_script” to run the whole file, then add “var Jk = JN[‘V’](this[‘Y’][0xced + 0x83 * 0x4a + -0x32ca])
, Jk = Ja[Fh(bc.F)](Jw, Jk, JQ);”, get an error, said “no JN blabla”
